Systemic Bibersteinia (Pasteurella) trehalosi infection was diagnosed in a weaned lamb suddenly died in the late spring. The diagnosis was based on the isolation of the bacterium from the affected organs, and the evidence of gross pathological and histological lesions. The bacterium was detected in the lamb first with immunohistochemical method by using rabbit hyperimmune serum raised against B. trehalosi serotype 3. Bacteria were observed extracellularly in large number in the necrotic foci of liver, and in necrotic areas of tonsil and nasal mucosa. The bacteria were demonstrated in large number in the cytoplasm of inflammatory cells situated in the alveoli and bronchioli in the lung. The bacteria were present in low amount in the spleen, mediastinal lymph node, kidney and ileum, while they were absent in the heart muscle and brain.
